The "Crocodile Splice Unit" is a Diamond device (patent pending) which provides a simple way to repair and install fiber optic fibers and cables as well as to add cable extensions to existing fiber optic installations. When used for repairs, replacing already installed cables can be avoided. This remarkably reduces maintenance expenses and wasted time while re-establishing interrupted fiber optic connections. The "Crocodile Splice Unit" is a further development of the well-known crocodile alberino fusion system and can be terminated using the ZEUS D50 Fusion Field Termination Kit and only a few additional tools and accessories.
